CHARLES J. ARMSTRONG, AUSTIN, TEXAS, ASSIGN OR OF ONE-HALF TO CHARLESWOLF, SAME PLACE.

COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 591,720, dated October12, 1897. Application filed. March 25, 1897. Serial No. 629,267. (Nomodel.)

To aZZ whom it may concern.-

Be it known that 1, CHARLES J. ARMSTRONG, a citizen of the UnitedStates, residing at Austin, in the county of Travis and State of Texas,have invented a new and useful Combination- Tool, of which the followingis a specification.

The invention relates to improvements in combination-tools.

The object of the presentinvention is to improve the construction ofcombination-tools and to provide a simple, inexpensive, and efficientdevice adapted without changing any of its parts to operate as a nut andpipe wrench, pliers, hammer, screw-driver, and nail-extractor.

The invention consists in the construction and novel combination andarrangement of parts, as hereinafter fully described, illustrated in thedrawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of a combination-toolconstructed in accordance with this invention, the jaws being shown inengagement with a nut. Fig. 2 is a side elevation illustrating anothermanner of engaging a nut.

Like numerals of reference designate correspondin g parts in bothfigures of the drawings.

1 and 2 designate bars or members connected between their ends by apivot 3 and provided at the latter with circular enlargements, and thelatter have peripheral notches 4, forming cutting edges at thecontiguous faces of the enlargements and adapted for cutting wire. Thenotches provide a wirecutter at each side of the tool for theconvenience of the operator, and a piece of wire may be rapidly outwithout changing the po- I sition of the tool in the hand and withoutreversing it.

The handle portion of the bar 1 is tapered to provide a screw-driver,and the handle portion of the bar 2 has a claw 5 at its end forextracting nails.

The jaws 6 and 7 of the bars 1 and 2 are provided at theirinner portionswith opposite serrated or toothed notches 8, which are curved and whichare adapted to engage a pipe or rod in order that the device may beemployed as a pipe-wrench or pliers, and by opening and closing the jawsthe device is adapted. to be readily adjusted to suit the diameter ofthe rod or pipe to be operated on.

The outer portions of the'jaws 6 and 7 are disposed at a slight angle tothe inner portions thereof. The jaw 7 is provided at its outer extremitywith an inner flat checkered face 9, and the other jaw 6 is providedwith an inwardly-extending lug 10, having a checkered face to cooperatewith the fiat face 9, in order that the device may be used as a pair ofpliers. The lug 10 also forms a recess and cooperates with the straightface ll of the extension of the arm 6 in receiving and engaging onecorner of a nut, as illustrated in Fig. 1 of the accompanying drawings.The other jaw is provided with a series of angular recesses 12, disposedon the arc of a circle and adapted to engage the opposite corner of thenut 13. The straight face 11 extends from the lug 10 to the innerterminus of the angular extension of the jaw 6, and the jaws are adaptedto be open to a greater or less extent to bring any one of the series ofnotches 12 to a point opposite the recess formed by the lug 10 and theextension of the jaw 6 to suit the size of the nut to be gripped.

In order to adapt the device for engaging nuts of sizes which are notaccommodated by the notches or recesses 12, the jaw 6 is providedbetween the extension and the recesses or notches 8 with straight faces14 and recesses or notches 15 and 16, and the other jaw is provided withrecesses or notches 17 and 18. By this construction the jaws are adaptedto engage the larger sizes of nuts, as illus trated in Fig. 2 of thedrawings.

The jaw 6 is provided at its outer edge with an elargement 19, having astraight hammerface and also adapted to strengthen the jaw. A taperingprojection 20 is provided at the inner end of the hammer-face forengaging staples to enable them to be readily extracted.

It will be seen that the device is simple and comparatively inexpensivein construction, that it is adapted for use as a nut or pipe wrench,pliers, hammer, wire-cutter, staple and nail extractor, andscrew-driver, and that the device does not require removal of any of itsparts or the substitution of other parts in order to adapt it for any ofits uses, and that the adjustment is efiected by simply opening andclosing the jaws.

WVhat I claim is A device of the class described comprising the pivotedbars or members provided with jaws having angular extensions at theirterminals, one of the jaws being provided with a continuous curvedseries of notches 12, 17 and 18 to receive a corner of a nut, and theother jaw 6 being provided at the extension 1 with a flat inner face 11and an inwardly-extending lug 10, forming a shoulder to engage the outeredge of a nut, said jaw 6, being also.

my own I have hereto afiixed my signature in the presence of twowitnesses.

CHARLES J. ARMSTRONG.
